Project Thread: Morphine Prototype

[SHiFT]

Ok that's good to hear. Makes me feel a LOT better. The batteries are up at 49.xxx volts right now. I am using a Meanwell, the small one, and input is 29.xx amps according to the hyperion menu. The menu says the batteries are only at about 87% charge.
Amps are set to 10.0a, it is what the menu had set as the default for a 10,000mah 12s battery.

Thanks,

Yes, 5000mAh is nothing, I basically got 4 test runs in today, and decided not to run the battery out too much. This relates to the "almost" dying part - but I touched the soldering gun, the soldering clamps annnnnd... both leads of the other LIPO battery. Yes, it sparked in my face. Yes, it instantly melted the contact points on the soldering clamp and the leads of the battery. Yes, I felt like I almost died. And no, I'm not touching that battery again. I am a noob with anything related to this, and even more so with LIPOs. I'm not taking the chance using a battery that might have sustained damage and just ordering another one. In the meantime, I'm running on one.

To be honest mate I think the battery would probably be fine, so long as the short was for a brief moment. do you have a lipo charger that can check the IR of the pack? How long did the flash last? do you recall if the pack got warm at all?

I, and quite a few others from what Ive read have on occasion shorted out lipos for brief periods. And yea, its one way to get the adrenalin pumping!!! In my case I had decided to test my connectors, before sliping the cover on 'em.... just plain stupid. luckily the flash was only for a moment, and apart from a bullet connector with a gaping chasm down one side there was no harm done. the discharge wires and pack didnt even get slightly warm, and it didnt change their IR or capacity at all. And I've been using it for months since with no issues.

Your pack is fine. The wire blew as a fuse would. The pack is fine.

I actually plugged two packs together once. WOW was that freakin CRAZY!!!!

Both packs were fine. The wires exploded, but the packs were fine.

lol. new marketing ploy... 'lipo packs, now with built in 4mm fuses!!'

Haha. K, thanks for the info. It's good to know in case I ever do that again.

I did not see anyone tell you to not bolt through a tube, ever. It will just crush the tube unless you weld a small piece of pipe in the frame where you are clamping. And welding on Al is no good.

That's great advice, never thought of that. I did the PVC route this time, but now I know for the future.

Thanks.

I finally finished my bike. It's not elaborate, but it's done for the most part. Thanks so much for all the advice and assistance, I'd never have even started this project were it not for the information and expertise available here.
